Although a State's actual agricultural export value cannot be measured directly, ERS maintains estimates of State shares of U.S. exports for total and selected individual commodities based on U.S. farm cash-receipts data. ERS has discontinued updates of an alternative fiscal-year (October to September) series of State export estimates based on State and commodity shares of production, but continues to provide the historical estimates based on that methodology. The Documentation page describes both the current cash receipts-based method and the discontinued production-based method.
The commodities and commodity categories for which state-level exports are listed reflect the availability of public cash receipts data at the state and national level. In addition, commodities with less than $2 billion in export sales at the national level are aggregated into a category labeled “Other plant products,” which includes sugar products, tobacco, other grains, other oilseeds, other oilseed products, planting seeds, other horticultural products, and processed foods (including wine). In some cases, state exports of an individual product in the “Other plant products” category could rank among the leading exports from the state, particularly if that product is produced by only a few states.
The files below provide the annual State export estimates using the new U.S. farm receipts-based method for 2000-2013 as well as the historical estimates using the discontinued U.S. agricultural production-based method for 1990-2010.
Commodity changes in the 2013 update: The commodity coverage included in the 2013 update of State Export Data reduces the number of commodity groups from 20 to 23. Tree nuts are now combined with processed fruits into “Fruits and nuts, processed,” because of changes in the way 2013 cash receipts data are reported. Tobacco, planting seeds, and sugar products are shifted into “Other plant products” because U.S. exports in these categories are below the $2 billion cutoff used to determine inclusion as a separate category. See the Documentation page for a complete list of changes in the 2013 update.
